“The project describes how to build a 1x3 flip-disc display and how to control it via Arduino.
The design of the 1x3 flip-disc display is based on the project describing a single module (1 disc). The principle of control is the same with the difference that in order to minimize the number of Arduino control lines, a 595D shift register was used.
Flip-disc displays require a specific power supply, in order to flip the disc we need to supply the disc with a current pulse of about 0.5A with a precise length of about 1ms (see flip-disc datasheet) and with correct polarity.
The basics of controlling flip-disc displays and the principle of operation are described on the Flipo.io website dedicated to flip-disc displays and here.”
